The Problem with Longitudinal Data
My question is, are you like my college, where we identify a special cohort (usually tied to our reaffirmation of accreditation cycle) and follow it to get results at the start of the self-study period? Or do you have an entire series of these studies, so you also have 5-year, 4-year, ..., 1-year data?
AFAICT, we do not do the latter, but we do run smaller studies of everyone taking a particular course to identify issues and (with a different group) see what happens after some innovation has been tried.
I think my actions might soon create a Terms of Service violation for your website from Google.
In seeking to create as much traffic for my website as possible, I engaged in manipulative SEO practices which understandably resulted in Googles penalty.
The penalty may soon spread to your website as a result of the backlinks to findyourartschool.com which can be found at the following locations:
I am deeply sorry for any harm I may have caused, but I remain confident that this problem can be fully resolved if you remove the backlinks as soon as possible.
In doing so, both of our websites will be brought into better alignment with Googles guidelines and our search visibility will be restored.
I would be glad to assist you or answer any further questions or clarifications that you might need.
I urge you to contact me if you need any assistance or upon the deletion of the backlinks.
Thank you and sorry once again.

Also, the only thing worse than having longitudinal data is not having them.
If you see something coming down the pipe, like some sub-cohort that you might want to track for some reason (a new admit planning to transfer to a specific school under one your new programs), you want an ERP that allows you to add or modify a field so there is a convenient sorting flag.
I know that it requires a major effort to look at differences in differences when the treatment group can only be identified by course/section numbers for a given term, like when looking at the longitudinal effects of a trial pedagogy or hybrid etc.
